groups achieve a higher level of cooperation when they democratically select the partner matching protocol by voting …

Learning in finitely repeated games of cooperation remains poorly understood in part because their dynamics play out … over a timescale exceeding that of traditional lab experiments. Here, we report results of a virtual lab experiment in … majority of rational players. These results shed hopeful light on the long-term dynamics of cooperation, and demonstrate the …

More than half a century after the first experiment on the finitely repeated prisoner's dilemma, evidence on whether … cooperation decreases with experience–as suggested by backward induction–remains inconclusive. This paper provides a meta …-analysis of prior experimental research and reports the results of a new experiment to elucidate how coop- eration varies with the …

In repeated games, reciprocity helps to sustain group cooperation. Using the Markovian strategy as a touchstone, we … explore the evolution of cooperation in the infinitely repeated and noisy n-person Prisoner's Dilemma. With some modified game …

Intelligence affects social outcomes of groups. A systematic study of the link is provided in an experiment where two … initial cooperation rates are similar, it increases in the groups with higher intelligence to reach almost full cooperation … differences in the response to past cooperation of the partner. In higher intelligence subjects, cooperation after the initial …

We study the effect of network formation on cooperation in the finitely repeated prisoner’s dilemma based on the game …-theoretical model approach. We suggest the model explaining the effect of endogenous network formation on cooperation. We find a subgame … perfect strongly pairwise-Nash equilibrium in which cooperation is achieved by the trigger strategy based on non …

way to enforce cooperation in groups is ostracism: players who defect are expelled. If the group's members prefer not to … threat in doubt. Nonetheless, we show that ostracism can be effective in promoting cooperation with either finite or infinite …

hampers cooperation, as higher intelligence players are less cooperative once they are made aware that they play against …
